Hmmmm. I could've sworn when I hooked everything up there was a wire labelled "POW ANT" and I connected it. I'll have to double-check, but as far as I can recall, I don't get AM reception at all now and I did before.ColonelPanic wrote:Barring a not-great tuner, one thing to look at is whether you connected the power antenna lead on the harness that plugs into the car. These cars have an antenna amplifier to work around use of the shorter antenna. If your aftermarket radio isn't sending power to the proper pin on the factory harness, reception will be reduced as the amplifier will not be on.
Does this thing have an AM tuner? Usually AM reception is nonexistent if the antenna amplifier is not powered up.
I don't recall if you have moon & tunes. The audio amp and antenna amp use the same pin on the car harness so if that's not connected you wouldn't be complaining about lack of reception as you wouldn't know your tuner sucks as there would be no sound at all.
I don't know which wires are which on the harness, though--I stupidly threw out the bag it came in, which had a list of which coloured wires correspond with which functions.ColonelPanic wrote:If you have the power antenna lead coming out of your radio's harness, you could just use that.
James, thank you so much for your post!ColonelPanic wrote:Barring a not-great tuner, one thing to look at is whether you connected the power antenna lead on the harness that plugs into the car.

If you hook up to the auto antenna power wire, the antenna booster will only be activated when you're listening to the radio. If you use the power amp control, the booster will be active whenever the stereo is on. Doesn't really matter, but I'd use the auto antenna power wire.canadave wrote:I finally got around to trying to tackle this. I pulled the Eonon GE01 radio, and I see that there is a blue/black wire that I never hooked up, labelled "POW-AMP", that the manual describes as "Power amplifier control". There is another blue/black wire (same colour, right next to it) that I never hooked up, and the manual describes it as "Auto antenna power". The two wires are spliced together--they come out of the radio as one wire, but then are split so that they are separate wires to be used separately.
On the Metra harness for the Vibe, I have only two unused wires. One is blue/white, the other is orange/white. There is only one black wire coming out of the harness, and it is the GND wire, hooked up to the GND wire coming out of the Eonon radio.
So...do I hook up just the "auto antenna power" wire, or the "power amplifier control" wire, or both? What wire on the harness do I hook the wire(s) up to, I wonder? The blue/white wire coming out of the harness?
I'm not 100% sure what's going on with your wiring harness, but you want the power antenna wire coming out of the back of the radio to connect up to the black B3 "Antenna Amplifier Supply" wire on the factory wiring.canadave wrote:Wait a second...this makes no sense. How would it make a difference in terms of which of the two wires coming out of the Eonon I hook the blue/white wire from the wiring harness up to? The two Eonon wires are both spliced into the same wire going into the Eonon. So no matter which one I connect the wiring harness to, I will still be making the same connection--from the blue-white wiring harness wire to the Eonon.
So I'm not sure what difference it makes. I'm so confused!
The Power Antenna wire from the stereo needs to connect to the black wire going into B3. It doesn't matter how they connect, and it doesn't matter what color the wires in between are. What matters is that the +12V signal getting out the radio on the power antenna wire makes it to the black wire on the other side of B3.canadave wrote:That's the thing. There's no BLACK wire coming out of B3 position on the third-party wiring harness. It's a blue wire with white stripe.
As for the Eonon--there's a blue wire that comes from it, which "splits" (appears to be spliced, covered by a heat shrink) into two wires, both of which are coloured blue with black stripe. One wire is labeled "POW-AMP" and is described in the manual as being the "power amplifier control". The other wire is unlabeled, but the manual says it's the "auto antenna power" wire.
So which is the "power antenna wire" that you're saying I should connect out the back of the radio?
Copper is copper. Your knowledge of electricity indicates to me that this is an install you should not be undertaking yourself.canadave wrote:Right...what I'm getting at is, it doesn't appear to matter which wire I connect the B3 wire to. Whether I connect the B3 wiring harness wire to the "POW-AMP" wire, or the power antenna wire, those two both wind up being "the same wire" once it enters the Eonon, since they are spliced together (the two wires merge together before they enter the Eonon radio). So I guess it doesn't matter which one I solder to the B3 wire?
The reason I ask is because the POW-AMP wire is much longer--I had snipped the other wire thinking that I wasn't going to need it. So it would be easier for me to just use the POW-AMP wire to solder to the B3 wiring harness wire.
Just please make sure connections are solid, particularly the main ground, and all bare copper is fully insulated. Marginal connections have a way of heating up and starting fires, as do wires that have simply been cut and unused without being taped closed.canadave wrote:Well, I don't think I'm *that* bad. I soldered the POW-AMP wire to the wiring harness's B3 wire, and it works.
Thank you for your help.
